SAMUEL B. GOFF, OF EAST GREEK,- NEW JERSEY.

WINDMILL.

SPECIFICATION forming part of Letters Patent No. 223,725, dated January 20,

Application filed November 7, 1879.

To all whom it may concern Be it known that I, ,SAMUEL B. GOFF, a citizen of the United States, residing at East Creek, in the county of Cape May and State of New Jersey, have invented a new and useful Improvement in Windmills, of which the following is a specification.

My invention relates to that class of wind mills in which the wheel revolves in a vertical plane and the nature of the invention mainly consists in the combination, by means of a cord, rod, or equivalent device, of pairs of sails, which are pivoted at each end and in the middle horizontally, and have a weighted edge, whereby each sail throughout the whole series is so controlled as to be brought to and kept in a vertical position, or nearly so, and thus to receive squarely on its broad side next to the wind the whole force thereof while, passing through the upper part of the circuit above the axis of the Wheel. The lower half of the circuit is protected by means of a screen in the usual manner.

The invention further consists in .a novel mode of adjusting the rudder by lTlBElDSOf a polygonal hub 011 the upper end of the vertical central shaft of a revolving frame which supports the wind-wheel, the lower edge of the rudder having a corresponding recess, which engages with said hub.

When an adjustment of the rudder is to be made it is lifted out of its connection with said hub by means of a cord, one end of which passes over a pulley connected with the stationary frame of the mill, the other end being extended to a convenient place forits manipulation.

In the accompanying drawings, which make a part of this specification, Figure 1 is a side elevation of the wind-wheel, the revolving frame B, and stationary frame A. Fig. 2, Sheet No. 2, is an end elevation of the same, a portion of the frame A being broken away to exhibit the wheel clearly. Fig. 3 is a side elevation, on an enlarged scale, of the upper end of the central shaft, 0, the pulley L, and a portion of the rudder E. Fig. 4 is a horizontal section at the broken line 00 m of Fig. 3.

Like letters of reference in all the figures indicate the same parts.

A represents the standing frame of my improved mill; B, a revolving frame connected therewith by means of the vertical revolving shaft (3, the lower end of which connects with the step b in the sill of said frame A, and is supported near its upper end ina bearing in the upper part of the frame. D D are the sides of the wind-wheel, which have stud or There are an desirable number of airs of sails G connected with the side pieces, D D, of the wheel by means of pivots d in the ends of the sails.

There are cords or rods H, which are connected at their ends with the edge e of pairs of sails G at opposite sides of the wheel, as clearly seen in Fig. 1. These connected edges are weighted by means of metallic strips 0,

for the purpose of bringing the sails into a vertical position and retaining them in that position while they are passing through the upper part of their circuit above the annular screen I, and also to stiffen the edge. The

position of the sails causes their weighted edge to be in front of the line of motion of the wheel while the latter passes through the lower half of the circuit. To reverse their position is the Office of the cords H, which is done by the tendency of each sail to keep in a vertical position, exerting a p idling-force as it comes to the point as before passing behind the screen I, by means of the cord H upon the opposite sail at the point so, and thus to turn it over on its pivots before the latter comes above the screen to receive the force of thewind on its broad side.

E is the vane on the upper end of the vertical shaft 0 for regulating the position of the wheel to bring the sails G square with the wind or on an angle therewith, as may be desired. I

For a convenient, simple, and quick adjustment of the vane I connect its socket f at its lower edge with the hub g of the shaft, (seen in Figs. 3 and 4,) the nut having any desirable number of sides, so as to vary the position or angle of the vane by withdrawing the vane upward to clear the socket f from the hub g and giving the vane a partial turn around on the shaft 0 to make the alterations, and then again connecting the socket with the hub.

The withdrawal of the vane I effect by means of the cord K and pulley L, one end of the cord being attached to the vane, as seen in Fig. 1, and the other end being at any desirable position for manipulating it. The pulley L is connected with the yoke M, which has a permanent connection with the frame A; or the pulley may be held by any other convenient device.

I claim as my invention- 1. In a wind-wheel running-in a vertical plane, the combination of a series of pivoted sails having metallic weight-strips e atone edge, substantially as set forth.

2. The combination of the cords or rods H with pairs of sails G, the ends of the cords being connected with weighted edges of the sails, substantially as and for the purpose set forth.

3. The combination of the vane E with the shaft 0, connected thereto by means of the polygonal hub gand corresponding socket f, for the adjustment of the vane in its position to the wind-wheel, substantially as and for the purpose set forth.

4. The combination of the cord and pulley L with the vane E and yoke M, substanticlly as and for the purpose set forth.
